In this paper we present a feature set for Gamma-ray and Background Hadron events automatic classification. We selected the best parameters combination collected by Cherenkov telescopes in order to make a robust Gamma-ray recognition against different signal noise levels using multiple Machine Learning approaches for pattern recognition. We made a comparison of the robustness to noise for four classifiers reaching an accuracy up to \(90.14\%\) in high noise level cases.
